We report on the case of an extraordinary orangutan who spontaneously produced over a thousand drawings in 5 years. This female orangutan, Molly, started drawing when she was estimated to be 50 years old. Although it has been established that great apes spontaneously draw without training, she produced an enormous number of paintings in her old age, and the numbers of lines and colors in her drawings varied from day to day. As her drawings seemed to be affected by her surroundings, we attempted to analyze quantitatively relationships between her drawings and potentially influential factors during a specific period in which no ostensibly major events were observed. According to our results, her drawings were affected by the identity of her keeper, implying that her drawing behavior may have been affected by environmental factors. Thus, drawings may serve as windows to the internal states of non-human primates.
我们报告了一只非凡的猩猩的案例，它在5年里自发创作了一千多幅画作。这只雌性猩猩莫莉，据估计在50岁时开始画画。虽然已经确定大猩猩无需训练就能自发画画，但她在老年时创作了大量画作，而且她画作中的线条数量和颜色每天都有所不同。由于她的画作似乎受到周围环境的影响，我们试图在一个未观察到明显重大事件的特定时期，定量分析她的画作与潜在影响因素之间的关系。根据我们的结果，她的画作受到饲养员身份的影响，这意味着她的绘画行为可能受到了环境因素的影响。因此，绘画可能成为了解非人类灵长类动物内心状态的窗口。
